Technical Field

[0001] This application relates to the field of wire clamping technology, and in particular to a clamping assembly and a terminal crimping device. Background Technology

[0002] Terminal crimping equipment is a specialized device for crimping terminals onto stripped wire cores. It is widely used in wire harness manufacturing for home appliances, automobiles, and industrial control systems to achieve fast, low-resistance, and secure connections between wires and plugs, fuse boxes, and PCBs, while also ensuring high-speed batch production and stable consistency.

[0003] In the current wire cutting and terminal crimping processes, the wire is relatively thin and soft, making it unstable during clamping and causing unnecessary displacement. This leads to inconvenience in each process and affects the progress and consistency of subsequent processing. Utility Model Content

[0004] This application provides a clamping assembly and a terminal crimping device to solve the problem that during the wire cutting and terminal crimping process, the wire is relatively thin and soft, and is unstable during clamping, causing unnecessary displacement of the wire, which in turn causes inconvenience in each process and affects the subsequent processing progress and consistency.

[0005] In a first aspect, this application provides a clamping assembly for clamping wires, comprising: Clamping seat; A locking element, wherein the locking element is disposed on the clamping seat; A clamping member is provided, which forms a clamping space with the clamping seat. The clamping space is used to clamp the wire. The clamping member is movably disposed on the clamping seat. The free end of the clamping member can be connected or separated from the locking member so that the clamping space can fix or release the wire.

[0006] Optionally, the clamping seat includes a base portion and a bottom holding portion. The base portion has an installation groove, and the bottom holding portion has the clamping space. The bottom holding portion is located within the installation groove, and the bottom holding portion is made of a flexible material.

[0007] Optionally, the side wall of the mounting groove is provided with a limiting boss, and the bottom holding part is provided with a limiting groove, and the limiting boss is engaged in the limiting groove.

[0008] Optionally, the clamping member includes a movable part and a top holding part, the movable part having a receiving groove, the top holding part being located within the receiving groove, and the top holding part being made of a flexible material.

[0009] Optionally, the clamping member is rotatably connected to the clamping seat, and a first elastic member is provided between the locking member and the clamping seat. The two ends of the first elastic member are respectively connected to the locking member and the clamping seat, and the locking member is used to abut or release the free end.

[0010] Optionally, the locking member has a guide surface at the end away from the clamping seat, and when the clamping member is closed, the free end abuts against the guide surface to stretch the first elastic member.

[0011] Optionally, the locking member is provided with a locking part, and the free end is provided with a mating part, wherein the locking part can cooperate with the mating part.

[0012] Optionally, the clamping assembly further includes a second elastic element, the two ends of which are respectively connected to the clamping element and the clamping seat.

[0013] Secondly, this application provides a terminal crimping device, comprising: Base; A shaping and cutting module is disposed on the base and is used to shape and cut the wire. A terminal module is disposed on the base and is used to perform terminal crimping operations on the shaped and cut wire. A mobile positioning module is used to move the wire to the shaping and cutting module and the terminal module. The mobile positioning module includes a carrier, which is disposed on the base and has a snap-fit ​​groove. The clamping assembly provided in the first aspect of this application is engaged with the snap-fit ​​slot.

[0014] Optionally, the carrier is slidably disposed on the base, and the moving positioning module includes a driving member for driving the carrier along the vertical direction on the base.

[0015] The technical solutions provided in this application have the following advantages compared with the prior art: The clamping assembly provided in this application includes a clamping base, a locking member, and a clamping member. The clamping base, as the basic support structure of the entire clamping assembly, is typically made of rigid materials such as metal or high-strength plastic to ensure its stability and service life. One end of the clamping member is movably mounted on the clamping base via a hinge, pin, or other suitable connection method, allowing it to rotate or swing around the connection point. The free end of the clamping member is designed with a structure that mates with the locking member, such as a slot, a boss, or a smooth pressure surface. When clamping a wire, the operator or automated mechanism places the wire in a preset area on the clamping base. This area, together with the corresponding position of the clamping member, forms a clamping space for accommodating the wire. Subsequently, by operating the locking member, it connects or engages with the other end of the clamping member, thereby firmly clamping the wire between the clamping member and the clamping base. When wire release is required, the locking mechanism is reversed, releasing its constraint on the clamping mechanism. The clamping mechanism then returns to its initial position under its own elasticity, gravity, or external restoring force, increasing the clamping space and allowing the wire to be removed or replaced. This clamping assembly has a simple and compact structure, making it easy to manufacture and integrate into existing terminal crimping equipment. The ingenious combination of the clamping base, locking mechanism, and clamping mechanism enables reliable clamping and rapid release of the wire, facilitating operation and improving the efficiency of wire harness processing. The way the clamping space is formed ensures that the wire is subjected to relatively uniform pressure during clamping, reducing the risk of insulation damage or core damage due to excessive local pressure, thus guaranteeing the quality and reliability of the wire connection.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The following disclosure provides numerous different embodiments or examples for implementing various structures of this application. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0023] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0024] To address the technical problem in the prior art where, during the cutting and terminal crimping processes of wires, the relatively thin and soft wires are unstable during clamping, causing unnecessary displacement and resulting in inconvenience in each process and affecting the progress and consistency of subsequent processing, this application provides a clamping assembly 100. This assembly includes a clamping base 1, a locking element 2, and a pressing element 3. A clamping space 1a for accommodating the wire is formed between the clamping base 1 and the pressing element 3. By manipulating the pressing element 3 to move on the clamping base 1, its free end connects or engages with the locking element 2, thereby firmly clamping the wire between the pressing element 3 and the clamping base 1.

[0025] Figures 1 to 6 A clamping assembly 100 provided in this application embodiment is used to clamp wires, including: a clamping base 1, a locking member 2, and a pressing member 3; the locking member 2 is disposed on the clamping base 1; the pressing member 3 and the clamping base 1 enclose a clamping space 1a, the clamping space 1a is used to clamp wires, the pressing member 3 is movably disposed on the clamping base 1, and the free end 34 of the pressing member 3 can be connected or separated from the locking member 2 so as to fix or release the wires in the clamping space 1a.

[0026] In this embodiment, the clamping assembly 100 includes a clamping base 1, a locking member 2, and a pressing member 3. The clamping base 1, as the basic support structure of the entire clamping assembly 100, is typically made of rigid materials such as metal or high-strength plastic to ensure its stability and service life. The locking member 2 is disposed on the clamping base 1, and its specific form can be various mechanical structures, such as a cover with one end rotatable around the support base, a slidable pin, or a threaded locking mechanism. One end of the pressing member 3 is movably mounted on the clamping base 1 via a hinge, pin, or other suitable connection method, allowing it to rotate or slide around the connection point. The free end 34 of the pressing member 3 is designed with a structure that cooperates with the locking member 2, such as a groove, a boss, or a smooth pressure surface.

[0027] When wire clamping is required, the operator or automated mechanism places the wire in a preset area on the clamping base 1. This area, together with the corresponding position of the clamping member 3, forms the clamping space 1a for accommodating the wire. Subsequently, by operating the locking member 2, it interacts with or engages with the free end 34 of the clamping member 3, thereby maintaining the clamping member 3 in a depressed state, closing the clamping space 1a, and firmly clamping the wire between the clamping member 3 and the clamping base 1. When it is necessary to release the wire, the locking member 2 is operated in reverse to release its constraint on the clamping member 3. The clamping member 3 can then return to its initial position under its own elasticity or external restoring force, opening the clamping space 1a to the outside world, allowing the wire to be removed or replaced.

[0028] The clamping assembly 100 in this embodiment has a simple and compact structure, making it easy to manufacture and integrate into existing crimping equipment 200. Through the ingenious combination of the clamping base 1, locking member 2, and clamping member 3, reliable clamping and rapid release of the wire can be achieved, making operation convenient and helping to improve the efficiency of wire harness processing. The formation of the clamping space 1a ensures that the wire is subjected to relatively uniform pressure when clamped, reducing the risk of insulation damage or core damage due to excessive local pressure, thereby ensuring the quality and reliability of the wire connection. The cooperative design of the locking member 2 and the clamping member 3 provides sufficient clamping force, effectively preventing displacement or loosening of the wire during subsequent processes such as cutting, stripping, or crimping terminals, ensuring processing accuracy and consistency. Since one end of the clamping member 3 is movably connected and the free end 34 is detachable, this design allows the assembly to adapt to wires of different diameters or types (within a certain range). Simply changing or adjusting the contact surface shape or size between the clamping member 3 and the clamping base 1 can achieve effective clamping of wires of different specifications, enhancing the versatility and flexibility of the equipment.

[0029] Please see Figures 1 to 3In order to enable the clamping assembly 100 to clamp the wire more firmly, the clamping base 1 includes a base part 11 and a bottom holding part 12. The base part 11 has a mounting groove 1b, and the bottom holding part 12 has a clamping space 1a. The bottom holding part 12 is located in the mounting groove 1b and is made of flexible material.

[0030] In one embodiment, the seat portion 11 serves as the main frame of the clamping base 1 and is typically made of rigid and wear-resistant materials, such as metals (e.g., aluminum alloys, stainless steel) or high-strength engineering plastics (e.g., POM, nylon reinforced with glass fiber), formed by casting, machining, or injection molding. A mounting groove 1b, matching the shape of the base support portion 12, is provided on the top or working surface of the seat portion 11. The depth and width of the mounting groove 1b are slightly larger than the corresponding dimensions of the base support portion 12 to ensure that the base support portion 12 can be smoothly placed within it. The inner wall of the mounting groove 1b can be designed as a smooth surface, or it can be provided with small positioning protrusions or grooves to enhance the stability of the base support portion 12 after installation and prevent unnecessary shaking or displacement during operation. The base support portion 12 is made of a flexible material, such as silicone, rubber, polyurethane, or other polymer materials with good elasticity and toughness. On the upper surface of the bottom holding part 12, one or more clamping spaces 1a are provided for accommodating and initially positioning the wire. The shape of the clamping space 1a can be a V-groove, a U-groove, a semi-circular groove, or other shapes that are adapted to the cross-section of the wire. Its size should be slightly smaller than the diameter of the wire to be clamped, so as to utilize the elasticity of the material to achieve pre-tightening and initial fixation.

[0031] The clamping base 1 of this application, through the aforementioned structural design, particularly the combination of a rigid base body and a flexible bottom support 12, uses a flexible material and has a dedicated clamping space 1a. This allows the wire to be cushioned and initially positioned by wrapping it, effectively preventing scratches or pressure damage to the wire's insulation layer caused by rigid contact. It is especially suitable for handling wires with fragile or delicate surfaces. The flexible bottom support 12 provides a certain degree of elasticity and self-adaptability. The clamping space 1a can deform within a certain range, thus better adapting to wires of different diameters (within its elastic deformation range), enhancing the versatility of the clamping base 1 and its tolerance to wire size fluctuations. The bottom support 12 is housed within the mounting groove 1b of the base body 11. This split structure facilitates the quick replacement of bottom supports 12 of different specifications or materials according to the characteristics of different wires (such as diameter and material hardness) without replacing the entire clamping base 1, reducing equipment maintenance costs and changeover time, and improving production efficiency. In addition, the rigidity of the base 11 ensures the structural stability and positional accuracy of the entire clamping base 1, while the flexibility of the bottom holding part 12 provides necessary protection and adaptability. The combination of the two enables the clamping base 1 to achieve reliable clamping while also protecting the wire and providing flexibility in use.

[0032] Please see Figure 3 and Figure 6 The side wall of the mounting groove 1b is provided with a limiting boss 111, and the bottom holding part 12 is provided with a limiting groove 12a, and the limiting boss 111 is engaged in the limiting groove 12a.

[0033] In this embodiment, the mounting groove 1b of the base portion 11 protrudes inward along its two opposite sidewalls to form a limiting boss 111. The limiting boss 111 can be integrally formed with the base portion 11, and its specific form can be a long strip-shaped protrusion, spaced block protrusions, or annular flanges. For example, a long strip-shaped protrusion extending along the length of the groove can be provided on each of the front and rear sidewalls of the mounting groove 1b. The cross-section of the protrusion is semi-circular or rectangular, ensuring structural strength while avoiding occupying too much installation space. A limiting groove 12a adapted to the limiting boss 111 is provided at the corresponding position of the bottom support portion 12. The shape and size of the groove are completely matched with the limiting boss 111. For example, a long strip-shaped through groove or blind groove is provided corresponding to the long strip-shaped protrusion, and a dot-shaped groove is provided corresponding to the block protrusion. The depth of the groove is slightly greater than the height of the boss, leaving room for assembly.

[0034] The mating structure of the limiting boss 111 and the limiting groove 12a enables rapid and precise assembly of the bottom support 12 and the base 11 without the need for additional fasteners or adhesives. This simplifies the assembly process, improves assembly efficiency, and ensures the consistency of the bottom support 12's position after each assembly, preventing assembly deviations from affecting wire clamping accuracy. The tight engagement of the boss and groove effectively restricts the displacement of the bottom support 12 in all directions within the mounting groove 1b. Even under high-speed operation, vibration, or clamping force, the bottom support 12 remains stable, ensuring the positional stability of the clamping space 1a. This prevents positioning deviations in the wire due to displacement of the bottom support 12 during processing, improving the consistency of subsequent processes such as terminal crimping. This split positioning structure facilitates the disassembly and replacement of the bottom support 12. When it is necessary to adapt to different specifications of wires or when the bottom support 12 is worn, the bottom support 12 can be directly pulled out in the reverse direction of assembly for replacement. The operation is convenient and does not require modification of the base 11, which reduces maintenance costs and equipment downtime. At the same time, the cooperation between the boss and the groove can also disperse the force generated during the clamping process, reduce local wear of the bottom support 12, and extend its service life.

[0035] Please see Figure 1 , Figure 2 as well as Figure 4 In order to clamp the outer periphery of the wire from all directions, the clamping member 3 includes a movable part 31 and a top holding part 32. The movable part 31 has a receiving groove 31a, and the top holding part 32 is located in the receiving groove 31a. The top holding part 32 is made of flexible material.

[0036] In one embodiment of this application, the movable part 31 serves as the main body of the clamping member 3 and is typically made of a rigid material such as metal or high-strength plastic to provide sufficient structural support and driving force transmission. A receiving groove 31a is provided on the side of the movable part 31 facing the wire to accommodate the top holding part 32. The shape of the receiving groove 31a can be rectangular, arc-shaped, or other shapes that match the shape of the top holding part 32. The top holding part 32 is made of a flexible material, such as silicone, rubber, or polyurethane, and its shape is adapted to the receiving groove 31a so that it can be tightly embedded and securely positioned. The clamping surface of the top holding part 32 facing the wire is machined into an arc-shaped groove that fits against the outer circumference of the wire. When the clamping member 3 moves downward under the action of the driving mechanism or manual flipping, this arc-shaped groove can wrap around the wire from above. Simultaneously, the bottom holding part 12 of the lower clamping seat 1 also has a corresponding arc-shaped groove. In this way, the two flexible arc-shaped grooves work together to apply pressure from multiple points on the outer periphery of the wire, thereby achieving all-round, wrap-around clamping of the wire.

[0037] This application achieves the following significant benefits by designing the clamping member 3 as a combination of a rigid movable part 31 and a flexible top holding part 32, along with a flexible bottom holding part 12 below. This arc-shaped clamping surface design, with flexible material on both the top and bottom, can apply uniform pressure from all sides of the wire, achieving true "all-around clamping." This greatly enhances the stability and reliability of the clamping, effectively preventing radial offset, torsion, or axial movement of the wire during processing, thereby ensuring the accuracy and consistency of subsequent terminal crimping positions. The flexible top holding part 32 and bottom holding part 12 together form a buffer interface, providing sufficient clamping force while effectively absorbing impact and vibration during clamping, and increasing the contact area with the wire surface. This not only avoids damage or scratches to the wire insulation layer, protecting the integrity of the wire, but also helps improve the uniformity of the clamping force, making it particularly suitable for handling thin, soft, or fragile wires. Furthermore, the top gripper 32 is designed as a replaceable component, allowing users to quickly replace the top gripper 32 with a clamping surface of the corresponding size and curvature according to different diameters or types of wire, without having to replace the entire clamping component 3. This greatly improves the versatility and flexibility of the equipment, reduces production changeover costs and time, and improves the overall efficiency of the production line.

[0038] Please see Figure 1 and Figure 2 In order to enable the clamping member 3 to quickly lock and separate from the locking member 2, the clamping member 3 is rotatably connected to the clamping seat 1. A first elastic member 4 is provided between the locking member 2 and the clamping seat 1. The two ends of the first elastic member 4 are respectively connected to the locking member 2 and the clamping seat 1. The locking member 2 is used to abut or release the free end 34 of the clamping member 3.

[0039] In this embodiment, the movable part 31 of the clamping member 3 is rotatably connected to the clamping seat 1 via a pivot or hinge, allowing the clamping member 3 to rotate around the connection point, and its free end 34 to swing up and down to approach or move away from the bottom holding part 12 of the clamping seat 1. The locking member 2 adopts a sliding or rotatable structure, such as a columnar locking pin, a plate-shaped locking plate, or an L-shaped locking hook, which is assembled on the clamping seat 1 through a mounting structure or guide structure and can move or rotate in a preset direction. The first elastic member 4 is selected from compression springs, torsion springs, or elastic rubber blocks, etc. If it is a compression spring, its two ends are connected to the clamping seat 1 and the locking member 2 respectively; if it is a torsion spring, it is sleeved on the rotating shaft of the locking member 2, and its two ends are respectively engaged in the lugs of the locking member 2 and the slots of the clamping seat 1. Under normal conditions, the first elastic element 4 is in a pre-compressed or pre-torsional state, pushing the locking element 2 to remain in the abutting position, so that the top or hook of the locking element 2 is pressed against the abutting surface or slot of the free end 34 of the clamping element 3, thereby locking the clamping element 3; when it is necessary to release, a reverse force (such as pressing or flicking) is applied to the locking element 2 to overcome the elastic force of the first elastic element 4, so that the locking element 2 is disengaged from the free end 34 of the clamping element 3, and the clamping element 3 flips to release the wire under the action of manual or reset mechanism.

[0040] This application utilizes the pre-tightening force of the first elastic element 4 to achieve normal locking, eliminating the need for additional fasteners. Locking can be released simply by pressing or flicking, making the entire process fast and efficient. This meets the high-speed mass production requirements of the crimping terminal equipment 200, significantly reducing the switching time between wire clamping and release. The elastic abutment locking method has excellent self-adjustment capabilities, compensating for assembly errors between the clamping element 3 and the locking element 2, ensuring the stability of the locked state, preventing loosening due to vibration during equipment operation, thus guaranteeing the reliability of wire clamping and preventing wire displacement during processing. This structure is simple, with highly versatile components; for example, different specifications of the clamping element 3 can be adapted to the same type of locking element 2 and first elastic element 4, reducing design and manufacturing costs and facilitating maintenance, allowing for quick replacement of damaged elastic elements or locking elements 2.

[0041] Please see Figure 2 and Figure 5 In order to enable the clamping member 3 to be pressed and locked as a whole, the locking member 2 has a guide surface 21 at the end away from the clamping seat 1. When the clamping member 3 is closed, the free end 34 of the clamping member 3 abuts against the guide surface 21 so that the first elastic member 4 is stretched.

[0042] In one embodiment, the locking member 2 adopts a columnar or plate-shaped structure, and a guide surface 21 is integrally formed at the end away from the clamping seat 1. The guide surface 21 can be set as an inclined surface, an arc-shaped surface or a wedge-shaped surface. The free end 34 of the clamping member 3 is provided with an abutment end (such as a flat surface or an arc-shaped convex surface) that fits against the guide surface 21. When locking is required, a downward pressing force is applied to the free end 34 of the clamping member 3, causing the clamping member 3 to flip and cover around the rotation connection point with the clamping seat 1. At this time, the abutment end of the clamping member 3 contacts the guide surface 21 of the locking member 2 and generates relative sliding. The guide surface 21, through the guiding effect of the inclined or curved surface, converts the vertical pressure of the clamping member 3 into a lateral force that drives the locking member 2 to move in a preset direction (such as the horizontal direction), thereby stretching the first elastic member 4 (such as a tension spring, elastic rope, etc., with the two ends of the tension spring hooked to the hanging hole of the locking member 2 and the hanging post of the clamping seat 1, respectively). When the clamping member 3 is fully covered, the stretching force of the first elastic member 4 drives the locking member 2 to reset, so that the side away from the guide surface 21 abuts against the limiting surface of the free end 34 of the clamping member 3, thereby locking the clamping member 3.

[0043] With the cooperation of the guide surface 21 and the clamping member 3, clamping and locking can be achieved simultaneously with a single pressing action, eliminating the need for additional manual operation of the locking member 2. This simplifies the operation process and is particularly suitable for the linkage control of automated terminal crimping equipment 200 or the rapid operation requirements of manual operation, significantly improving the efficiency of wire clamping. The design of the guide surface 21 makes the pressing process smoother, effectively dispersing the force and avoiding component wear caused by local stress concentration. At the same time, the tension-reset locking of the first elastic member 4 has a self-tightening effect, which can compensate for the gaps caused by assembly errors and component wear, ensuring the stability of the locked state and preventing locking failure due to equipment vibration or external interference. This ensures accurate positioning of wire clamping and improves the consistency of terminal crimping.

[0044] Please see Figures 1 to 5 The locking member 2 is provided with a locking part 22, and the free end 34 of the pressing member 3 is provided with a mating part 33. The locking part 22 can cooperate with the mating part 33.

[0045] In this embodiment, the locking part 22 of the locking member 2 can adopt various adaptation structures, such as an annular locking platform, a wedge-shaped locking block, or an L-shaped hook protruding from the side wall of the columnar locking member 2, or a slot opened at the end of the plate-shaped locking member 2; correspondingly, the mating part 33 of the free end 34 of the pressing member 3 is configured to adapt to the locking part 22. If the locking part 22 is an annular locking platform, the mating part 33 is an annular groove opened at the free end 34 of the pressing member 3, and the outer diameter of the annular locking platform matches the inner diameter of the annular groove to ensure a tight fit; if the locking part 22 is a wedge-shaped locking block (the wedge angle is set to 20°-30°), the mating part 33 is a wedge-shaped notch that fits against the wedge-shaped locking block, and the inclined surfaces of the locking block and the notch engage with each other to achieve locking; if the locking part 22 is an L-shaped hook, the mating part 33 is a hanging post or a slot protruding from the free end 34 of the pressing member 3, and the hook can be hooked onto the hanging post or inserted into the slot. When the clamping member 3 is closed, the locking member 2 moves and stretches the first elastic member 4 under the action of the guide surface 21. After the clamping member 3 is fully closed, the first elastic member 4 resets and drives the locking member 2 to move, so that the locking part 22 and the mating part 33 are precisely aligned and form a fitting, hooking or snapping engagement, thereby achieving reliable locking of the clamping member 3. When unlocking, the locking member 2 is driven to disengage from the mating part 33, and the clamping member 3 can be released.

[0046] The precise fit design of the locking part 22 and the mating part 33 significantly improves the reliability and stability of the locking. Through a concrete interlocking, hooking, or snap-fit ​​structure, multi-dimensional limiting constraints are formed, avoiding slippage problems that may occur with simple elastic contact. Even when the equipment is running at high speed, experiencing severe vibration, or subjected to external interference, the locking state remains intact, ensuring the stability of the wire clamping and preventing wire displacement during processing from affecting crimping accuracy. Secondly, the diverse mating structures can adapt to different scenario requirements. For example, the fit between the annular clamping platform and the annular groove is suitable for scenarios requiring circumferential positioning; the fit between the wedge-shaped clamping block and the notch has a self-tightening effect; and the fit between the L-shaped hook and the hanging post facilitates quick disassembly. Users can select the appropriate structure based on requirements such as clamping force and operating frequency, enhancing the versatility and adaptability of the components.

[0047] Please see Figure 2 In order to enable the clamping member 3 to quickly reset after the locking member 2 is unlocked, the clamping assembly 100 also includes a second elastic member 5, the two ends of which are connected to the clamping member 3 and the clamping seat 1, respectively.

[0048] In one embodiment, the second elastic element 5 can be a torsion spring, a compression spring, or a tension spring. For example, if a torsion spring is used, it can be sleeved on the rotating shaft connecting the clamping member 3 and the clamping seat 1, with one end of the torsion spring abutting against the side wall of the clamping member 3 and the other end abutting against the corresponding protrusion of the clamping seat 1. When the clamping member 3 is locked, the torsion spring is in a torsional storage state. Alternatively, if a compression spring is used, one end can be fixed to the bottom or side of the clamping seat 1, and the other end can abut against the free end of the clamping member 3 or the lower surface near the free end, so that the spring is in a compressed state when the clamping member 3 is closed. When the locking member 2 releases the constraint on the clamping member 3, the second elastic element 5 releases the stored elastic potential energy, generating a restoring force that causes the clamping member 3 to rotate upward about its rotation axis, thereby driving the clamping member 3 to quickly return to the initial open position, preparing for the next insertion of wire.

[0049] The introduction of the second elastic element 5 enables the automatic and rapid reset of the clamping element 3, eliminating the need for manual lifting and greatly simplifying the operation process. This is particularly suitable for the cycle time requirements of automated production lines, significantly improving overall processing efficiency. This automatic reset function ensures that after each clamping operation, the clamping element 3 returns to a fixed and predictable initial position. This helps guarantee the consistency and accuracy of the next wire placement and clamping, thereby improving the processing quality and stability of the entire crimping process. Furthermore, the elastic force-driven reset avoids equipment malfunctions or processing errors that may result from improper manual operation or forgetting to reset, enhancing the reliability and safety of equipment operation.

[0050] Secondly, please refer to Figure 7 This application provides a terminal crimping device 200, including a base 201, a shaping and cutting module 202, a terminal module 203, a moving and positioning module 204, and a clamping assembly 100 provided in the first aspect of this application; the shaping and cutting module 202 is disposed on the base 201 and is used to shape and cut wires; the terminal module 203 is disposed on the base 201 and is used to crimp the shaped and cut wires; the moving and positioning module 204 includes a carrier 6 for moving the wires to the shaping and cutting module 202 and the terminal module 203, the carrier 6 is disposed on the base 201, and a snap-fit ​​groove 6a is formed on the carrier 6; the clamping assembly 100 snaps into the snap-fit ​​groove 6a.

[0051] In this embodiment, the base 201 of the terminal crimping device 200 is integrally formed from cast iron or high-strength aluminum alloy, serving as the installation reference for each functional module. Its top has a flat mounting surface and multiple threaded mounting holes for easy module position adjustment. The shaping and cutting module 202 is fixed to the front end of the base 201 by bolts. Specifically, it can adopt a combination structure of roller shaping components and cutting blade assembly. The roller shaping components include symmetrically arranged shaping rollers used to press the wire into a preset straight shape. The cutting blade assembly uses pneumatically driven upper and lower cutting blades made of high-speed steel, with the cutting length accuracy controlled by a stroke limit block. The terminal module 203 uses a stamping terminal crimping machine, installed in the middle of the base 201. Its crimping mold can be replaced according to the terminal type, adapting to the crimping requirements of different specifications of terminals such as insert type and ring type. The carrier 6 of the mobile positioning module 204 is a long strip of metal plate, which is slidably connected to the base 201 via a linear guide rail. It can move along the length and width of the base 201. The carrier 6 has a snap-fit ​​groove 6a, which is a T-shaped groove or a dovetail groove. The bottom of the seat part 11 of the clamping assembly 100 is provided with a T-shaped protrusion or a dovetail protrusion that matches the snap-fit ​​groove 6a. The snap-fit ​​is fixed by the interference fit between the protrusion and the snap-fit ​​groove 6a. The spacing of the clamping assembly 100 can be adjusted by sliding along the snap-fit ​​groove 6a to adapt to the processing requirements of wires of different lengths.

[0052] Please see Figure 8 The support member 6 is slidably disposed on the base 201. The moving positioning module 204 includes a driving member 7, which is used to drive the support member 6 along the vertical direction on the base 201.

[0053] In one embodiment, the carrier 6 is slidably mounted on the base 201 via a linear guide rail or a guide shaft slider. Specifically, a multi-layer sliding structure can be provided to enable the carrier 6 to slide in four directions (front, back, left, and right) on the base 201, allowing for quick adjustment of the carrier 6's position on the base 201 and enabling position adjustment of the carrier 6 during different working states. The driving component 7 of the moving positioning module 204 is used to drive the carrier 6 to move along the vertical direction (i.e., up and down) on the base 201 to achieve the lifting and lowering of the clamping assembly 100. Specifically, the driving component 7 can be a cylinder, an electric cylinder, or a servo motor combined with a ball screw or other linear drive mechanism. If a cylinder is used, the cylinder body can be vertically fixed to a specific position on the base 201 with bolts, and the top of the cylinder piston rod is connected to the bottom of the carrier 6. When compressed air enters the cylinder's inlet, the piston rod extends, pushing the carrier 6 along with its clamping assembly 100 upwards along a preset guide post or linear guide rail, allowing the wire to reach the designated processing height (such as the crimping position of the terminal module 203). When descent is required, the airflow direction is changed by controlling the solenoid valve, causing the piston rod to retract under spring force or air pressure, resetting the carrier 6. To precisely control the lifting height, a magnetic ring switch can be installed on the cylinder, or a mechanical limit block can be set at the end of the stroke to achieve position detection and stroke protection. The design of the drive unit 7 driving the carrier 6 to move vertically allows the clamping assembly 100 to precisely switch the wire between different height stations, for example, from the initial height of the shaping and cutting station to the crimping height of the terminal module 203, or to descend after completing a process to facilitate wire replacement or preparation for the next process. This greatly enhances the flexibility and automation of the equipment, enabling the smooth implementation of complex multi-station processing flows. By precisely controlling the lifting height of the carrier component 6, it can be ensured that the wire is in a fixed and optimal processing position during each processing run, thereby guaranteeing the depth and positional accuracy of the terminal crimping and improving the consistency of product quality. Furthermore, integrating the drive component 7 into the motion positioning module 204 makes the equipment structure more compact, reduces unnecessary space occupation, and also facilitates subsequent equipment upgrades and functional expansions.
